Nice scene and colors. But the banding on the flowerstems is killing it. The colorcount is pretty high, with plenty of redundancies. In a mockup composit; colorsplurging can be granted some license...but drawn-from-scratch scenes (as implied here) commands greater palette-disciplin. Still, you got some nice stuff. :)

You did an awesome job on the detail of the Snake, The Boss and the background, all while still being able to tell the difference between the stage and the characters. Very impressive stuff, nice work!
